HP StoreEver MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries User and Service Guide (AK378-96059, December 2012)

Figure 1 Library Extender installed with two MSL4048 Tape Libraries
The extender occupies the lower half-height drive bay of the upper library and the top half-height
drive bay of the lower library.
The upper library controls the extended library and is called the master library. The extended
library uses only the master library OCP, USB port, and Ethernet connection.
The lower library is controlled by the master library. The lower library OCP, USB port, and Ethernet
connection are not used by the extended library.

If you are using the encryption kit with both libraries and then install the extender, you will need
to combine the encryption keys onto a single key server token. The extended library only uses the
USB port and key server token in the master library; the USB port in the lower library is inactive.
See the encryption kit user guide for instructions on combining the encryption keys from both key
server tokens onto a single token. If the number of keys on the two tokens is greater than 100, use
the Number of Keys to Backup option to generate a backup file with a subset of the keys from one
of the tokens to restore to the other token.

The MSL8048 can be upgraded to the capacity of an MSL8096 with TA739A, the HP MSL8048
